Daily consumption of at least 3 grams of oat beta-glucan reduces total and LDL cholesterol levels by 5-10% in normocholesterolemic or hypercholesterolemic subjects.

To lower your cholesterol, aim for at least 3 grams of oat beta-glucin daily. This is roughly equivalent to one and a half cups of cooked oatmeal or a high-fiber oat cereal. For best results, consume it in a liquid form like oat milk or mixed into a smoothie, as liquids maintain the viscosity needed to bind cholesterol. Ensure your overall diet is low in saturated fats to maximize the benefit.
